Look through your wheel well (or jack the car up and remove the wheel if you have to) and examine the pads that are snug against the metal rotor. Generally, if the brake pad is between a quarter inch to an eighth of an inch thick, you should replace it. If you do replace one pad in the front or back, make sure to replace both to ensure even wear.
- Park the car in a clean, dry place. First, loosen all lug nuts for both front wheels using the tire iron that came with your car (in the trunk).
- Either ride the car up on wheel ramps, or jack up the front of the car using two car jack stands. Always be sure to place blocks behind the rear wheels, and make sure to only use the jacks against the solid frame under the car.

- Rub the rotor with your finger to check for any grooves or scoring. Make sure the rotor isn’t hot before you touch it! If there are grooves, you should also remove the rotor for replacement as well. Once you’ve removed the brake pads, and potentially the rotors, from each wheel, you’re ready to go to the auto store to purchase new parts. Bring everything with you.

- Once the caliper is reset, reinstall the new rotor in place of the old one. When you install the new brake pads onto the caliper, make sure to spread some of the grease between the plate and clips and the brake pad itself.
- After you’ve installed the new rotors (if you had to), and reassembled the new brake pads mounted back onto each caliper, you’ve finished the job!
- Carefully lower the car back to the ground, remove the blocks from the rear wheels and go for a test drive!
